do with a third conflict. and, in fact, in the u.s. military was ordered to undertake a no-fly zone, you are talking about a conflict. you're talking about u.s. warplanes going over libya, bombing those sites, bombing the anti-aircraft sites and taking lethal action to keep the libyan air force from flying. but that said, the other problem is, there's very little stomach for the u.s. to get involved by other countries in the region. there's nobody really calling for u.s. military involvement in libya right now. and circling back, don, that's what puts the white house in a very tough spot. if libyan civilians come under sustained attack, very tough to stand by and watch that and not do anything. but what do you do? and that's the problem even as we speak. >> pentagon correspondent barbara starr, barbara, thank you. much more on the crisis in libya coming up tonight. join me and john vause as we co-anchor an hour-long special coming up at 10:00 p.m. eastern.
